Victorian American Romance and Breach of Promise

The more I study historic details of America's past, the more I realize I don't know--such as the common practice of suing for breach of contract when a young swain's courtship derails and no marriage results. I was fascinated by newspaper accounts of settlements upon jilted brides, the dollar amounts sued for, common beliefs of the time period about courtship in general. Who knew courtship in nineteenth century America was such a legal risk?
